Evaluation of the impact of the dietary inclusion of salty and sugary former food products on the liver and plasma profile of pigs through OMICS approaches

ABSTRACT: The research on alternative and sustainable feed ingredients is a challenge to reduce feed-food competition between humans and monogastrics, in particular pigs. Former food products (FFPs) drop out from the industrial production of food such as pasta, bread, snacks, and chips. They have a high nutritional and energetic value and represent an alternative and sustainable feed ingredient. The aim of this study was to apply omics tools to assess the impact of the dietary inclusion of FFPs in pigs’ diet. For the in vivo trial, thirty-six Swiss Large White male castrated pigs were randomly assigned to three dietary groups: control (CTR), 30% replacement of CTR diet with salty FFPs (SA), 30% replacement of CTR diet with sugary FFPs (SU). The trial lasted from the start of the growing phase (22.4 ± 1.7 kg) until slaughtering phase (110 ± 3 kg). After slaughtering, blood and liver tissue samples were collected and processed according to the omics approaches used. The number of differentially regulated proteins in each comparison matrix (SA/SU vs. CTR) indicated a marginal impact on liver function, as measured by proteomics on tissue samples. The peptidomics investigation on plasma samples showed low variability between the peptidome of the three dietary groups and identified three possible bioactive peptides associated with anti-hypertension in the SA dietary group. To conclude, the safety and the limited impact of the SA and SU diets on liver proteome and plasma peptidome strengthened the idea of recycling FFPs as feed ingredients to make pig production more sustainable.

Replacing cereals with food leftovers could reduce feed-food competition and keep nutrients and energy in the food chain. Former food products (FFPs) are industrial food leftovers no more intended for human but still suitable as alternative and sustainable feedstuffs for monogastric. In this study, omics approaches were applied to evaluate the impact of dietary FFPs on pig liver proteome and plasma peptidome. Thirty-six Swiss Large White male castrated pigs were randomly assigned to three dietar ...[more]

Project description:Sustainable aquaculture, which entails proportional replacement of fish-based feed sources by plant-based ingredients, is impeded by the poor growth response frequently seen in fish fed high levels of plant ingredients. To evaluate the potential to improve, by means of early nutritional exposure, the growth of fish fed plant-based feed, rainbow trout swim-up fry were fed for 3 weeks either a plant-based diet (diet V, V-fish) or a diet containing fishmeal and fish oil as protein and fat source (diet M, M-fish). After this 3-week nutritional history period, all V- or M-fish received diet M for a 7-month intermediate growth phase. Both groups were then challenged by feeding diet V for 25 days during which voluntary feed intake, growth, and nutrient utilization were monitored (V-challenge). The results of the V-challenge showed a higher growth rate and higher feed intake in fish of nutritional history V compared to M (see PMID:24386155). To identify the molecular mechanisms that govern the enhancement of feed acceptance following early-feed exposure of diet V, we performed microarray expression analysis using swim-up fry collected at the end of early-feeding exposure (diet M and diet V), as well as brain and liver of juveniles sampled at the end of the V-challenge (M-his and V-his), and employing a rainbow trout microarray platform with 8 X 60K probes per slide. Persistently differentially expressed genes were identified by isolating probes that were differentially expressed (fold change ≥ 1.5 and p {nutritional history} ≤ 0.05), both at the end of the early exposure, and in either brain or liver of juvenile trout at the end of the V-challenge. Overall, 1787 (3-week + Brain) and 924 (3-week + Liver) mRNA probes were found to be persistently affected by nutritional history of early-feeding exposure. This positive response is encouraging as a potential strategy to improve the use of plant-based feed in fish, of interest in the field of fish farming and animal nutrition in general. Furthermore, the genes associated with mediating this positive early feeding effect, could serve as potential biomarkers to evaluate increasing acceptability of plant-based diets in fish farming.
